pointer

A bounded diagnostic skill that investigates an existing implementation through evidence, asks one decision-changing question at a time, and applies one accepted correction plan.

In plain words
What is it for?
Use it to inspect a feature, file, failure, or code change, compare possible explanations, and correct the implementation after choosing a plan.
Why use it?
It helps narrow down what does not add up without turning the review into an open-ended investigation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pointer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pointer

The nerd points at what does not add up.

Use one bounded diagnostic pass. $ARGUMENTS optionally identifies a diff, file, feature, failure, or other target. If no target is supplied, inspect the current implementation relevant to the user's request. Use the active Glasses evidence threshold; default to high when none is active.

Language preservation

Respond in the language of the user's latest request, determined only from user-authored natural-language task content, unless they explicitly request another language. Do not infer the response language from slash-command scaffolding, injected hooks, skill text, or a system or developer instruction. Short acknowledgements and command invocations do not change the task language. Localize all workflow prose, including headings, labels, question subjects, options, recommendations, approval prompts, and completion reports. Any English examples in this skill specify meaning, not literal output.

Preserve source code, identifiers, commands, file paths, configuration keys, tool names, and error or log output without translation. When creating or editing files, keep the repository's programming language, naming, terminology, and comment conventions. Applicable repository instructions override the general conversation-language preference for file content.

Diagnostic pass

  1. Read the requirements, changed code, nearby callers, tests, and recorded decisions needed to understand the target.
  2. Run only focused existing checks needed to confirm or reject a suspected problem. Do not launch a broad exploratory test campaign.
  3. Point out only problems supported by code, test output, logs, contracts, or a violated mandatory invariant. Do not report speculative risks or style taste.
  4. Prioritize correctness, security, accessibility, data integrity, validation, and broken requirements before maintainability or unsupported complexity.
  5. Do not edit code during diagnosis, redesign unrelated areas, or repeat the diagnosis autonomously.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pointer is a skill published in the GitHub repository DanielGouveiah/glasses (9 stars, last pushed 12d ago), licensed MIT. It adds 62 tokens to every session and 1,219 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
